My invention relates to fastening devices for detachably securing theside rails of a bed to the bed ends.

The principal objects of my invention are to provide a connection of sosimple a forml that it may be readily assembled and taken apart byinexperienced persons; to avoid the necessity of using tools oi wrenchesin connecting or disconnecting the rails and bed ends; to dispense withloose parts; to insure a permanent rigid connection; to construct theparts of rolled or stamped metal and thereby eliminate possibility ofbreakage; to reduce the numberof parts to a minimum; to utilize the endof the side rail as a bearing face for holding the bed end in uprightposition; and to provide a neat and compact corner fastening which maybe readily a'pplied to various types of corner posts.

Referring to the drawings:

Fig. 1 is a side view of a corner connection embodying my improvements;

Fig. 2 a sectional View thereof, taken substantlally on the line 2-2 ofFig. l;

Fig. 3 a top view of the corner connection showing the construction ofthe remote end of the side rail;

Fig. 4 an enlarged detail view of the bracket seat for confining the endof the up- 30 right flange of the side rail; and

Fig. 5 a view similar to Fig. 2, showing the side rail in reverseposition.

On the drawings, the reference numeral 1 indicates a fragmentary portionof a tubularA bed post, 2 a side rail of theV bed and 3 a bracket forsecuring the side rail to the bed post. This bracket 3 comprises anupright elongated plate portion 4, the outer face of which is formed to'correspond to the form of the post to which it is to be attached,vin thepresent case the outer face of the plate 4 being concave to t thecircular post 1. This plate is clamped onto the post by cap screws 5, orrivets if desired, which are passed through apertures near the upper andlower ends of the plate 4 and through corresponding apertures in thewall o f the post 1 and are secured to a washer G inside the post, sovas to clamp the wall of the post between the late 50 4 and washer 6 Atthe outer edge o the 1923. Serial No. 643,075.

plate 4 the bracket 3 is formed with a wing 7 having a verticallyelongated notch 8 formed therein which is open at the top, the forwardedge of said notch being arranged at a slight angle to the plane of theplate 4 as shown in Fig. l, so as to afford a wedge action ashereinafter described, for clamping the end of the side rail against theplate 4. The bracket 3 is preferably of pressed or rolled metal and thenotch 8 is formed therein by stamping or punching the section of metalwithin the notch outwardly from the side wing 7 in such a manner thatthe front'bearing edge shears orf on a slight bevel as shown at 9.

The side rail 2 is in the form of an angle iron and has a headed stud 10secured to the upright Hange thereof a short distance from each end.This stud is arranged substantially midway between the upper and loweredges of the side fiange of the angle iron and is preferably somewhattapered as shown particularly in Fig. 3, to insure a tight fit in theaperture of the rail flange and also to cooperate with the bevel edge 9of the notch 8 so as to afford a lateral drawing of the upright flangeof the rail against the side wing 7 of the bracket, and the inner end ofthis stud is u set or riveted over against a washer 11 which is placedagainst the inner face of the upright flange `of the angle iron siderail.

` It is desirable in bed constructions to have the angle iron side railsarranged so that they may be reversed, that'is, so that they may bepositioned with the horizontal Hange at the top as shown in Fig. 2, orwith the horizontal flange at the bottom as shown in Fig. 5. In thepresent construction the end of the angle iron butts against the plateportion 4 of the bracket 3, and in order that the horizontal lange mayclear theupper cap screw or rivet 5, the ends of the angle iron arenotched as at 12, said notch being extended so that the inner sidethereof is substantially flush with the inner surface ofthe uprightiiange of the angle iron, and forms a tongue 13 at each end of the angleiron consisting of the end portion of the upright flange of the angleiron and also a narrow tongue 14 at each end A consisting of. an endportion of .the horiture of the side wing bracket 3 is formed with anupwardly exzontal flange of the angle iialiln.h Atlthe junlwit t e p ate4 t e tending flaring groove, channel or recess f15 of a formsubstantially as shown in Fig. 4, which is engaged bv the tongue orprojecting end 13 of the'upriglit flange of the angle iron when the stud10 isl engage in the wedging notch 8, said channel or rece s 15 beingadapted to confine the end ofthe tongue 13 and hold s ame rigidlyagainst lateral displacement. The engagement of the tapered portion ofthe stud 10 with the'beveled edge 9 of the notch 8\ serves at the sametime to. increase the rigidity of the connection by drawing the sideflange of the angle iron laterally against the side wing 7 of thebracket 3, such lateral i drawing action` being also supplemented by theengagement of the projection 'or tongue 14 of the horizontal flange ofthe angle iron 'against the plate portion 4 of the bracket, as thetongueor projection 13 of the upright flange is inserted into the seat 15.

It will' be observed that because the pin or stud projects laterally.from the plane of the vertical flange of the side rail, the'thrusts orreactions of the bracket parts against the end 13 of the flange andagainst the shank of the pin 10, are substantially out of line or oisetso as to provide a twisting couple or moment between the bracket and therail which also tends to draw the free endV of the wing 7 and thevertical flange of the. side rail in to intimate contact. There is notendency forthe end 13 ofthe side rail to slip on the plate part 4 oftbe bracket for the reason that the end 13 of the side rail is rigidlywedged or anchored in the groove l5.

e t is customary -to connect the two posts of each bed end by means of across rail which is usually located at Y' about the same elevation asthe side rail of the bed, and in my present construction th'is crossrail, which vis indicated at 16, is arranged somewhat below the lowestposition of the side rail 2, so as to afford ample clearance, and hasythe ends connectedl to the post 1 by means of the lowermost cap screwor rivet 5 which serves to secure the bracket 3 to the post. The sidewings 7 of the bracket 3 are positioned at the outer side of thetherefore concea the ends of the cross brace Y 16 and the parts whichconnect the brackets 4 side rail interl to the post 1, and the cornerfastening therefore resents a. neat compact appearance.

With this construction, it will be observed A late 4, and these sidewings z fan open top notch, an angle iron side rail havingan uprightflange and a horizontal flange, a lateral projecting stud on saidupright flange wedgingly engaging the notch of the wing 4member so as tojam the end edge of said flange nto'the aforesaid seat, said notch beingprovided with'a beveled bearing edge and the stud with a ta ered stemforjengagement with the beveled e ge whereby the upright flange oftheangle iron is wed edagainst the wing member of the brac et.

'In a bedstead corner fastening, the combination of a corner posthaving a bracket attached thereto, a portion of said bracket 'projectingtherefrom, said projecting portion having. an open-ended slot thereinformed'with an edge inclined toward the post at its lower end, said edgebeing beveled, and a side i'ail having a laterally projecting studhaving a ta red shoulder adapted to engage said bevele edge of said slot.whereby clamping en agement is effected between the side of sai railand said bracket and also between the end of said rail and anotherportioii of said'bracket.

3. In a bedstead corner fastening, the coinbination of'a corner post, abracket having a vertically .extending plate secured to the post and avertically extending win projecting outwardly from one side of'saiplate, and having an inclined slot formed therein, a side rail having anend part disposed against the inside of the wing and havin its extremityengaged in the angle of the racket, and a in secured to said end partand projecting aterally into. said slot to wedge said end part againstthe plate, the inter-engagin parts o the .pin and slot being relativelyveled so as to draw the end part into intimate contact with the wing.
